- Captain's log, stardate 5423.4.
- We are orbiting the planet Gideon, which is still not a member of the United Federation of Planets. The treaty negotiations have been difficult because Gideon has consistently refused the presence of a delegation from the Federation on its soil, or any surveillance by the ship's sensors. They have finally agreed to a delegation of one. They insisted it be the captain of the Enterprise. I am, therefore, beaming down at once.
- Log entry by James T. Kirk.
- I am alone on the Enterprise. I have searched every area of the ship and still cannot find a trace of the crew, or an indication of how its disappearance was managed. The one thing that is obvious is that I suffered a memory lapse, during which time I bruised my arm. It is causing me some irritation.
- Ship's log, stardate 5423.8.
- First Officer Spock reporting. Obviously the Gideons have transported Captain Kirk onto this replica of the Enterprise to so confuse his mind as to make him susceptible to some extraordinary experiment. It is my intention to locate the captain and warn him before the experiment reaches its conclusion, which logic indicates means the end of the captain's life as he knows it.

- The novelization by James Blish contains a scene where "Odona" (using the alternate spelling) accidentally burns off her finger with a medical instrument, and quickly re-grows the digit. This aspect of Gideonite physiology was not shown in the episode, although it was alluded that they did have a great resistance to injury. The prose version also added a scene where the crew proposes Odana will offer a symbol of illness to those she infects. The characters of Krodak and Fitzgerald were not named in the novelization.
- Actor Gene Dynarski (Krodak) had previously played Ben Childress and would later play Orfil Quinteros. Richard Derr (Fitzgerald) previously played Commodore Barstow.
- This episode marks the only time the bridge set was filmed empty, in this case representing the replica Enterprise. TOS episode: "This Side of Paradise" had previously showed the actual Enterprise bridge devoid of personnel, but with a single Omicron Ceti spore plant present.
